Nasel bone? Marker for Down syndrome?

Sydney

Hello, I had my 20 week ultrasound done almost two weeks ago and they were unable to see babies nasel bone so now I’m worried! This is the only side profile we got as she was being stubborn! What do you guys think? I’m only 20 second baby, and didn’t do any early testing or anything! I did have to schedule a follow up ultrasound that’s in 2 weeks
